I have a 400sbc I want to put in an 88 iroc with a t-5 I just bought but I can't seem to find a fly wheel that will fit the t-5 bell housing and I also need to know what starter to get for it as well. please help I really want to get this car up and running, lol

 

Well at least on mine, everything bolted right up. Used the stock flywheel. Aftermarkets are available too.

I even used the same starter that came with the 305.....

 

are you saying to use the stock 305 flywhell? I thought the 305's were internally ballanced and I know the 400's are externally ballanced so how does this work?

 

Mine bolted up. But my 400 has been internal balanced w/5.7 rods.

You didn't mention anything about what kind of balance your engine had in your original post. I know there's options with externally balanced 400's but I can't think of them off-hand. I think there;s a counterwieght you can get that bolts to the flywheel, and you have to have a 400 dampener. Try searching....I've read about this before a few times.

 

yea mine is already built and is externally ballanced. I will try searching but I spent half the day searching before I posted lol. I could find that people had to use a special flywheel but they didn't say where to get it.

 

does anyone know where to get the ballance plate or what it is really called???? I have looked every where with no luck.

 

How about this?

Or a new flywheel

Looks like the counterweights are for flexplates. Personally, the flywheel goofnrox posted is the way I'd go...

 

well if it works for a flexplate then it should work for a flywheel. if it balances the crank it balances the crank, right?

 

Do a search before you post.

Holy crap! I forgot that post!!!

I was even involved in it and forgot!

 

Correct; they work for either.

Remember that flywheel bolts are longer than flexplate bolts, and if you're going to add that weight to verify thread engagement.

 

I searched for half the day before I posted, I must not have put in the right search words but I did search, I always do.

 

I forgot to add that I am gonna get new flywheel bolts so that should not be a problem. thanks for everyones help. I just ordered the counter balance plate and new flywhell bolts from Summit, should be here right after X-mas

 

sometimes "generic" searches which return too many hits to find things easily work better with usernames. RB83L69 has tonnes of good info in his posts for example. I post lots about T56s, clutches, flywheels... Honestly when I know a topic has been hashed over several times, I just search for my username and "flywheel."

 

thanks for the info I will try that next time
